(A/N: Music starts here.)

??? (In Shadow's mind): Shadow! SHADOW!! SHADOW!!!

I look back at a different location as I now focus at the source of where the voice came from.

Me: Who are you?

??? (In Shadow's mind): I will explain soon. But for now, you can just call me flix. 

Me: (sigh) Alright, Flix. What is it?

??? (In Shadow's mind): I need your help. A world needs your help. More importantly, couple of worlds need your help.

Me: Why me?

Flix (In Shadow's mind): You are worthy.

I wield Muteki and Pandora Gauntlets as I snapped my finger, unleashing their Ultimate abilities.

Flix (In Shadow's mind): You are worthy to embark on a journey to retrieve the rest of the hundred Infinity Gauntlets scattered around the crossovers and the globe.

Me: I see.

I jumped over an army of COVER Entities (Kill la Kill Crossover) as I launched an ice and magma beam from Muteki Gauntlet to cover fire for the others who are saving victims who fell victim to the COVERS.

(A/N: COVER Entities.)

Flix (In Shadow's mind): You and the others are the only ones capable in defeating Thanos with the Avengers

Me: Uuuuh, we made an organization.

In another crossover, Kuyou (Rosario + Vampire Crossover) and Shadow clashed claws and gauntlets with each other during the battle skipping scenes to show the rest of Team STRM and Team RWBY supporting his area by keeping Kuyou's people busy from below the Academy

(A/N: Kuyou.)

Flix (In Shadow's mind): And what's your Organization or your group name, then???

Me: Well.... to put it in a serious note.....

Scene changes to see several cities from different crossovers are engulfed in flames. Scene changes to show Shadow standing at the stairs, lacking behind as Rias (Highschool DxD) turned to look at me as she had a puzzled look on her face.

(A/N: Rias Gremory.)

Rias: Shadow? Everything alright? You haven't answered my question.

He thought of Rubes, his friends, team and the World of Remnant when he opened his eyes as he said the name.

Me: The Remnant Defense League.

Flix (In Shadow's mind): I see.

Rias: I see. That's your group name.

Me: Yes. I'm the one who started the group/organization.

In the next few scenes, leaders of several crossovers gave Shadow the Infinity Gauntlets from specific crossovers. Scene changes as Shadow wields the Gremory Gauntlet and launched a beam at the Fallen Angels to cover Issei's back and another scene change as Shadow is in his Neptunia Beyond form and launch a beam at Arforie in her Giant Bomb mode.

(A/N: Issei Dragon Cardinal mode.)

(A/N: Arfoire's CPU Form.)

(Akame Ga Kill) Najenda: (Shows the Pure Stone (A/N: From Sheele's Weapons.)) Sheele was one of the best of us,... before she died.... Use here weapon..... wisely.... and take care of her.

(A/N: Najenda.)

Me: I will. That's a promise.

The scene changes when the Imperial Guards (Akame Ga Kill) were sliced by Extase to Night Raid's shock when they tried to see whowas wielding it until,--

(A/N: Extase.)

???: I'm sorry.... forgive me, Tatsumi....

Everyone looked with shocked faces.

Mine: Sh-Sheele???

Seryu: IMPOSSIBLE!!!!

Seryu's Imperial Arms charged in while Shadow in his Trinity Fusion Form (Shadow Wrath, Summer Rose and Sheele are components) combined Remnant Calibur and Extase together as he unleashed a powerful beam from the combined weapon itself. 

(A/N: Music ends here.)

Scene changed when Shadow left the Creepypasta crossover inside the portal when someone called out.

???: Help.... help me...

Me: Who are you? Identify  yourself???

???: HWAA!!! WHERE ARE MY GLASSES?!?!

I tilted my head in confusion as I noticed something floating towards me.

???: Oh, there it is.

Me: I got it.

As Iwent for it, I grabbed it, while noticing a spirit's hand grabbing it as well. I looked up as I let go of the glasses as the spirit worn them.

???: Well, let's start over, shall we? I'm Sheele.

(A/N: Sheele.)

Me: Oh, Shadow. 

Sheele: Nice to meet you. Anyway.... I need your help...
